If you're looking for stuff like Samsung TCCD quality, I'd say the best values are Mushkin (I saw it for $223 for 2x512MB at newegg) and Crucial Ballistix ($230 @ newegg for either PC3200 or PC4000). All of the rest are good, too, like Corsair, OCZ, PQI, Geil, etc, I just haven't seen them for sub- $250. Also, Crucial Ballistix are not TCCD, they are micron, but for some reason they work great on the A64 platform. There is a review on anandtech comparing them to other memory, and they seem to consistently have very tight timings at very high frequencies. Mine are in 2T because my bios is having problems running at 1T, but supposedly they can keep 1T timings up to very high speeds.
